Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to an integrated sewage treatment equipment for fishing ports. Background Technique

[0002] The sewage in fishing ports contains certain concentrations of organic matter, nitrogen, and phosphorus. The B / C value of the sewage is high, and its biodegradability is good. However, different from ordinary domestic sewage, the ammonia nitrogen ratio is relatively high. Therefore, the existing sewage treatment equipment of this type adopts an integrated treatment facility based on the AO coupling MBBR process. The fully automatic oil removal device configured at the front end can achieve integrated solid-liquid separation and oil-water separation to achieve the purpose of impurity removal and oil removal.

[0003] The existing integrated treatment equipment of this type integrates each treatment tank body inside a container-type box body. In order to facilitate the observation and maintenance of each link of this treatment equipment, many inspection ports are provided on the top of this container-type integrated treatment box body. Therefore, a climbing mechanism is provided at this type of box body to facilitate the operator to climb onto the box body for observation and maintenance. Most of the existing climbing mechanisms of this type are ladder structures. In order not to affect the mechanism of the entire box body, the top of these ladder structures will be slightly higher than the top end of the box body, and the ladder structures are mostly fixed to the box body by welding. Such a setting form makes it impossible for the operator to directly grasp the top of the ladder structure for support when climbing to the top of the box body and climbing down from the top of the box body. Therefore, the existing ladder structure of this type of treatment equipment is inconvenient to operate when climbing, and at the same time, during the process of climbing down, it is necessary to bend down to search for the grasping point at the top of the ladder structure. Such an operation of changing the body center of gravity will cause instability in standing or grasping, so there is a risk of falling. In view of this, an integrated treatment equipment is proposed.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a Figures 1-5 fishery port sewage integrated treatment device as shown, including an integrated treatment box 1. A liquid inlet 2 is arranged on the front of the top of the integrated treatment box 1, and a liquid outlet 3 is arranged on one side of the top of the integrated treatment box 1.

[0024] Specifically, a plurality of waste outlets 4 are arranged on the other side of the top of the integrated treatment box 1, and a plurality of inspection ports 5 are arranged on the top of the integrated treatment box 1.

[0025] It should be noted that, as Figure 5 shown, the integrated treatment box 1 used in this solution integrates a water collection pool, a grid well, an oil separation tank, an adjustment tank, a floating slag tank, an anaerobic tank, an anoxic tank, an aerobic tank, an MBBR membrane tank and a disinfection tank. During the process of treating fishery port sewage in this solution, the treatment flow direction of the sewage is successively: water collection pool, grid well, oil separation tank, adjustment tank, anaerobic tank, anoxic tank, aerobic tank, MBBR membrane tank and disinfection tank.

[0026] The main purpose of setting the water collection pool is to adjust the water volume and remove large impurities. Solid-liquid separation and oil-water separation are completed by a fully automatic oil-water separator: the oily sewage first enters the grid well and the oil separation tank from the water inlet of the water collection pool. The solid residues are filtered out by the fine grid and sent out for collection by the spiral conveyor trough; the wastewater continues to flow into the oil separation tank, and mechanical demulsification is carried out through the baffle. The electric heating device can ensure that the grease is in a continuous liquid state in the upper layer and is collected by the oil extension trough; the lower-layer static sewage enters the adjustment tank through the siphon device.

[0027] The treatment process adopts the anaerobic tank + anoxic tank + aerobic tank + MBBR tank + biological tank sedimentation process. The removal of pollutants such as organic matter, ammonia nitrogen, and total nitrogen mainly relies on the biological treatment process in the reactor.

[0028] In the anaerobic tank, the dissolved oxygen brought from the effluent of the aerobic tank, MBBR tank and the mixed liquid of biological filter sludge is mainly utilized to ensure the normal denitrification of the anaerobic filter bed. While deoxygenating, a further nitrification reaction is carried out; at the same time, the refluxed sludge is digested to provide a carbon source for denitrification and carry out partial denitrification; and the upper space of the anaerobic tank is used to precipitate the suspended solids in the influent; the excess sludge accumulated after digestion in the aerobic environment is digested, and phosphorus is not released during the digestion process, forming highly phosphorus-rich sludge, achieving a certain phosphorus removal effect.

[0029] In the anoxic filter bed of the anoxic tank, the microorganisms are in an anoxic state. At this time, the microorganisms are facultative microorganisms. They convert the organic nitrogen in the sewage into ammonia nitrogen, and at the same time use the organic carbon in the sewage as an electron donor to convert NO2ˉ-N and NO3ˉ-N in the sewage into N2, and also use part of the organic carbon source and NH4+-N to synthesize new cell substances. Therefore, the anoxic filter bed not only has a certain function of removing organic matter, reducing the organic load of the subsequent aerobic tank and MBBR tank to facilitate nitrification, but also relies on the relatively high concentration of organic matter existing in the sewage to complete denitrification, ultimately eliminating the eutrophication pollution of nitrogen.

[0030] In the aerobic tank and MBBR tank, since the concentration of organic matter has been greatly reduced, but there is still a certain amount of organic matter and relatively high ammonia nitrogen. In order to further oxidize and decompose the organic matter and ensure the smooth progress of nitrification when the carbonization is completed, an aerobic biochemical system with a low organic load is set up in the aerobic MBBR tank. In the aerobic MBBR tank, there are mainly aerobic microorganisms and autotrophic bacteria (nitrifying bacteria). Among them, the aerobic microorganisms decompose the organic matter into CO2 and H2O, and the autotrophic bacteria (nitrifying bacteria) use the inorganic carbon produced by the decomposition of the organic matter or CO2 in the air as a nutrient source to convert NH4+-N in the sewage into NO2ˉ-N and NO3ˉ-N. The effluent of the aerobic MBBR tank is refluxed to the deoxygenation tank to provide an electron acceptor for the anaerobic filter bed, and the nitrogen pollution is finally eliminated through denitrification, so as to achieve the purpose of finally removing pollutants such as BOD, COD, ammonia nitrogen, total nitrogen, and total phosphorus in the sewage.

[0031] After biological treatment, the sewage enters the biological filter for sedimentation and filtration to remove the SS in the sewage and make the final effluent meet the standards stably. Part of the sludge in the MBBR membrane tank is refluxed to the anaerobic filter, and the other part of the sludge is lifted to the sludge tank for aerobic digestion of the sludge and then regularly suctioned and transported out.

[0032] On the front of the integrated processing box body 1, there is a climbing mechanism for equipment inspection and maintenance. The climbing mechanism includes a ladder main body 6. The top of the ladder main body 6 is inserted and connected with an extended handrail 7. Between the insertion position of the extended handrail 7 and the ladder main body 6, there is a locking piece for fixing the insertion position of the extended handrail 7 and the ladder main body 6.

[0033] Specifically, on the top and bottom of the ladder main body 6 and on the side close to the integrated processing box body 1, there are a plurality of connecting blocks 601. The plurality of connecting blocks 601 are all used for fixedly connecting with the integrated processing box body 1.

[0034] Furthermore, between the middle parts of the two arms of the ladder main body 6, there are a plurality of cross beams 602 for climbing and stepping.

[0035] Specifically, on the top of the ladder main body 6, there is an insertion slot for the extended handrail 7 to be inserted. The size of the insertion slot matches the size of the rod wall of the extended handrail 7 in the vertical direction. In this way, the bottom of the extended handrail 7 can slide vertically and be inserted into the insertion slot. On one side of the insertion slot, there are a plurality of locking jacks 603 opened in the vertical direction for cooperating with the locking piece to complete the fixation of the insertion position.

[0036] Furthermore, on one side of the bottom of the extended handrail 7, there is a storage sliding slot 701. The inner walls at the top and bottom ends of the storage sliding slot 701 are both provided with limiting sliding slots. The locking piece includes:

[0037] A locking insertion rod 8. One end of the locking insertion rod 8 is slidably inserted and connected into the storage sliding slot 701, and the other end of the locking insertion rod 8 is slidably inserted and connected with one of the locking jacks 603.

[0038] A compression spring 10. A plurality of compression springs 10 are respectively arranged in a plurality of limiting sliding slots.

[0039] Still further, both the top and bottom ends of the locking insertion rod 8 are fixedly connected with limiting sliding blocks 9. The plurality of limiting sliding blocks 9 are respectively slidably inserted and connected into the plurality of limiting sliding slots. In the setting of this solution, the compression spring 10 is arranged on the side of the limiting sliding block 9 away from the locking jack 603 in the limiting sliding slot. In this way, the compression spring 10 always keeps pressing the limiting sliding block 9 in the direction close to the locking jack 603. Driven by the limiting sliding block 9, the locking insertion rod 8 can always maintain the locking insertion with the locking jack 603.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
